of difference between the average beaker sample and the average displayed
total. If the error is not rectified, clean the flow meter thoroughly and repeat the
procedure. Do not use water for this test. For most accuracy results,
calibrate using fluid to be measured with flowmeter.
If it is necessary to re-calculate a new k-factor
You will first need a data-collecting instrument to count pulses produced by the
flow meter. Trigger at least 500ml of your sample fluid in a steady stream at
approximately the desired flow rate into a graduated beaker.Divide the number of
pulses by the volume dispensed and the result is your new k-factor in the units
of your sample. In the example above, the k-factor units would be impulses/ml.
